Abstract
Mussel inspired polymerization of polydopamaine over Halloysite nanotubes (HNTs) support has been executed in this work. Such functionalized HNTs were in situ polymerized free radically in presence of sodium alginate as naturally occurring polysaccharide. Methacrylic acid has been grafted onto sodium alginate backbone by means of free radical redox triggered Michael type reaction. The dispersed functionalized HNTs in gel matrix have been clearly noticed by Transmission electron microscopy (TEM) analysis. The successful coating of HNTs has been supported by zeta potential measurement as well TGA analysis. Moreover, the semi‐IPN is biodegradable in nature within around 21 days of study. Most interesting feature of superstretchablity and reversible ductility has been imposed into the nanocomposite hydrogels which can infer them as soft rubbery biomaterial. Lastly the prepared hydrogel is showing effective pH‐responsive controlled release feature.
